Abstract： |
A transient stable control method for power system with superconductive energy-stroage device pertains to a transient stable control technique field based on current type inverter in a power system, characterized in that it puts forward a power system dynamic model with superconductive energy-stroage device; it obtains a robust control model of this system by leading into an external interference, then uses a linearization method and a linear H¡ý[¡Þ] control theory to restraint the external interference on the foundation that concerns the nonlinear essence in the system; and it may greatly raise transmission limit of the power system and its safety, strengthens transient stability of the systemat, and decreases the frequency instability of the power system or the accident of voltage collapse induced by a fault or other reason. |
